The multicomponent high entropy alloy films (HEAFs), CoCrFeMnNiMox (x=0, 0.05, 0.25, 0.5, 0.85), were prepared by co-sputtering of CoCrFeMnNi alloy and Mo targets. The content of Mo was controlled by the power applied on the Mo target. The effects of Mo addition on the crystal structure and hardness were investigated using X-ray diffraction and nanoindentation, respectively. The HEAFs exhibited a single FCC phase at lower Mo contents and eventually transformed to an amorphous structure with the increasing Mo content. The hardness increased from 6.53 GPa at x=0 to 8.77 GPa at x=0.85. However, the reduced modulus had a lowest value of 136 GPa at x=0.5. The strength and ductility of films were studied using micropillar compression tests.
